Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a water treatment module and a water treatment system. Background Art

[0002] In daily life, water channels are used to supply cold or hot water to faucets, providing users with water of different temperatures. In the prior art, water channels typically include a cold water channel and a hot water channel. The cold water channel delivers room-temperature domestic water to the faucet, while the hot water channel is equipped with a heating structure that heats the water in the hot water channel, allowing it to deliver hot water to the faucet. In actual use, the heating structure is typically spaced apart from the faucet, resulting in some water remaining in the hot water channel between the heating structure and the faucet. When the faucet is not delivering hot water, this water gradually cools in the hot water channel and becomes a cold water segment. When the faucet resumes delivering hot water, the cold water segment is delivered to the faucet before the hot water, resulting in a lower initial water temperature. This prevents users from quickly obtaining hot water, making it difficult to meet their hot water needs and reducing their user experience. For example, when using a faucet to deliver hot water to a cup, if the initial cup of water is too low to meet the user's needs, the user will often choose to refill the cup, which can easily waste water resources.

[0042] The technical solution of the utility model has the following significant beneficial effects:

[0043] When the water treatment module of the present invention is used, the water inlet is connected to the inlet of the fine filter assembly, and a booster pump is provided on the water inlet. The booster pump can pump water through the water inlet to the fine filter assembly for fine filtration treatment, thereby obtaining purified water. By connecting the normal temperature water outlet to the purified water outlet of the fine filter assembly, the purified water filtered by the fine filter assembly can enter the normal temperature water outlet and be delivered to the water mechanism for use by the user.

[0044] By connecting the water storage tank to the purified water outlet of the fine filtration assembly, purified water filtered by the fine filtration assembly can enter the water storage tank, and the purified water in the water storage tank can be heated by the heating element to obtain hot water. In addition, the water storage tank is connected to the hot water outlet waterway, and the hot water outlet waterway is equipped with a water pump. The water pump can transport the hot water in the water storage tank through the hot water outlet waterway to the water outlet mechanism for user use.

[0045] Since the water storage tank and the water outlet mechanism are connected via the hot water outlet waterway, if the water outlet mechanism stops delivering hot water for a certain period of time, the hot water in the hot water outlet waterway will gradually cool to room temperature water, forming a cold water section in the hot water outlet waterway. When the water outlet mechanism starts delivering hot water again, the cold water section in the hot water outlet waterway will be discharged before the hot water in the water storage tank, forcing the water outlet mechanism to discharge the cold water section before it can deliver hot water, resulting in users not being able to get hot water quickly, which reduces the user experience.

[0046] To address the aforementioned technical issues, the water treatment module of the present invention further includes a return water circuit, the water inlet of which is connected to the hot water outlet circuit, and the water outlet of which is connected to the upstream inlet of the water storage tank. The return water circuit allows water in the hot water outlet circuit to flow back upstream of the inlet of the water storage tank. In particular, when a cold water section exists in the hot water outlet circuit, the return water circuit allows at least part of the cold water section to flow back upstream of the inlet of the water storage tank. This reduces or eliminates the cold water section in the hot water outlet circuit, facilitates the rapid output of hot water from the water storage tank by the water outlet mechanism, and thus improves the user experience.

[0065] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0066] Implementation Method 1

[0067] Please refer to Figures 1 to 4As shown, an embodiment of the present invention provides a water treatment module, which includes a fine filter assembly 100, a water inlet waterway 200 with a booster pump 210, a normal temperature water outlet waterway 300, a water storage tank 400, a heating element, a hot water outlet waterway 500 connected to the water storage tank 400, a water pump 510 provided on the hot water outlet waterway 500, a water outlet mechanism 600 and a return waterway 700, the water inlet waterway 200 is connected to the inlet of the fine filter assembly 100; the normal temperature water outlet waterway 300 can be connected to the fine filter assembly 100; The clean water outlet of the filter assembly 100 is connected; the water tank 400 can be connected to the clean water outlet of the fine filter assembly 100; the heating element is used to heat the clean water in the water tank 400; the water pump 510 is used to drive the hot water in the water tank 400 to be output through the hot water outlet waterway 500; the water outlet mechanism 600 can be connected to the normal temperature water outlet waterway 300 and the hot water outlet waterway 500; the water inlet end of the return waterway 700 can be connected to the hot water outlet waterway 500, and the water outlet end of the return waterway 700 can be connected to the upstream of the inlet of the water tank 400.

[0068] Generally speaking, when the water treatment module is in use, the water inlet waterway 200 is connected to the inlet of the fine filter assembly 100. A booster pump 210 is provided on the water inlet waterway 200. The booster pump 210 can pump water through the water inlet waterway 200 to the fine filter assembly 100 for fine filtration treatment, thereby obtaining purified water. By connecting the normal temperature water outlet waterway 300 to the purified water outlet of the fine filter assembly 100, the purified water filtered by the fine filter assembly 100 can enter the normal temperature water outlet waterway 300 and be delivered to the water mechanism for user use.

[0069] By connecting the water tank 400 to the purified water outlet of the fine filter assembly 100, purified water filtered by the fine filter assembly 100 can enter the water tank 400. The purified water in the water tank 400 can be heated by a heating element to obtain hot water. Furthermore, the water tank 400 is connected to a hot water outlet passage 500, which is equipped with a water pump 510. The water pump 510 can deliver the hot water in the water tank 400 through the hot water outlet passage 500 to the water outlet mechanism 600 for user consumption.

[0070] Since the water storage tank 400 and the water outlet mechanism 600 are connected via the hot water outlet passage 500, if the water outlet mechanism 600 does not deliver hot water for a certain period of time, the hot water in the hot water outlet passage 500 will gradually cool to room temperature water, thereby forming a cold water section in the hot water outlet passage 500. When the water outlet mechanism 600 delivers hot water again, the cold water section in the hot water outlet passage 500 will be discharged before the hot water in the water storage tank 400, forcing the water outlet mechanism 600 to discharge the cold water section before it can deliver hot water, resulting in users being unable to quickly obtain hot water, which reduces the user experience.

[0071] To address the aforementioned technical issues, the water treatment module of the present invention further includes a return waterway 700, the water inlet of which is connected to the hot water outlet waterway 500, and the water outlet of which is connected to the upstream inlet of the water storage tank 400. The return waterway 700 allows water in the hot water outlet waterway 500 to flow back upstream of the inlet of the water storage tank 400. In particular, when a cold water section exists in the hot water outlet waterway 500, the return waterway 700 allows at least a portion of the cold water section to flow back upstream of the inlet of the water storage tank 400. This reduces or eliminates the cold water section in the hot water outlet waterway 500, facilitates the rapid output of hot water from the water storage tank 400 by the water outlet mechanism 600, and thus improves the user experience.

[0072] In the embodiment of the present invention, the designer can adjust the specific structure of the heating element according to the use requirements, and no specific limitation is made here. For example, the heating element is an electric heater, a heating tube, etc.

[0073] In the embodiment of the present invention, the designer can adjust the specific structure of the fine filter assembly 100 according to the use requirements, and no specific limitation is imposed here. Preferably, the fine filter assembly 100 includes an RO filter element.

[0074] In an embodiment of the present invention, the water treatment module further includes a hot water outlet valve 520 provided on the hot water outlet waterway 500 , and the hot water outlet valve 520 is located downstream of the water pump 510 .

[0075] By arranging the hot water outlet valve 520 on the hot water outlet waterway 500 , the hot water outlet valve 520 can be used to control the on / off state of the hot water outlet waterway 500 , thereby supplying hot water to the water outlet mechanism 600 in a controllable manner.

[0076] Designers can adjust the specific structure of the hot water outlet valve 520 according to usage requirements. For example, the hot water outlet valve 520 can be set as a solenoid valve, and no specific limitation is made here.

[0077] Furthermore, a water inlet control valve 230 is provided on the water inlet channel 200. The water inlet control valve 230 can control the on-off state of the water inlet channel 200.

[0078] In an embodiment of the present utility model, a normal temperature water branch 310 is provided on the normal temperature water outlet waterway 300 , and the normal temperature water branch 310 is connected to the inlet of the water storage tank 400 . The water treatment module also includes a water replenishment valve 311 , which is arranged on the normal temperature water branch 310 .

[0079] By setting a normal temperature water branch 310 on the normal temperature water outlet water path 300, the normal temperature water branch 310 can be used to connect the normal temperature water outlet water path 300 and the inlet of the water storage tank 400, so that the water in the normal temperature water outlet water path 300 is transported to the water storage tank 400, and then the heating element can be used to heat the water in the water storage tank 400 to obtain hot water.

[0080] Furthermore, by arranging the water replenishment valve 311 on the normal temperature water branch 310 , the water replenishment valve 311 can be used to control the on / off state of the normal temperature water branch 310 , thereby achieving a better water replenishment effect.

[0081] In a feasible implementation of the present invention, if Figure 1 and Figure 2 In the illustrated embodiment, the outlet end of the return water circuit 700 is connected to the normal temperature water branch circuit 310 located between the water replenishment valve 311 and the inlet of the water storage tank 400 .

[0082] By connecting the outlet end of the return water circuit 700 to the normal temperature water branch 310 located between the water replenishment valve 311 and the inlet of the water storage tank 400, the return water circuit 700 is used to make at least part of the cold water section in the hot water outlet water circuit 500 flow back to the upstream of the inlet of the water storage tank 400, thereby reducing or eliminating the cold water section located in the hot water outlet water circuit 500, making it easier for the water outlet mechanism 600 to quickly output the hot water in the water storage tank 400, thereby improving the user experience.

[0083] Furthermore, after at least part of the cold water section in the hot water outlet waterway 500 flows back to the water storage tank 400, the heating element can be used to reheat this part of water, thereby avoiding the problem of water waste and improving utilization.

[0084] The water pump 510 can play a one-way conveying role on the hot water outlet waterway 500 , so that the water in the hot water outlet waterway 500 can flow toward the water outlet mechanism 600 .

[0085] When the outlet end of the return water circuit 700 is connected to the normal temperature water branch 310 located between the water replenishment valve 311 and the inlet of the water storage tank 400, the driving action of the water pump 510 can make the cold water section in the hot water outlet water circuit 500 flow from the water inlet end of the return water circuit 700 to the water outlet end of the return water circuit 700, without the need for an additional power mechanism, thereby reducing equipment costs.

[0086] In another possible embodiment of the present invention, Figure 3 In the illustrated embodiment, the water treatment module further includes a post-filter assembly 320 disposed on the normal temperature water outlet waterway 300 , and the outlet end of the return waterway 700 is connected to the normal temperature water outlet waterway 300 located between the fine filter assembly 100 and the post-filter assembly 320 .

[0087] By utilizing the post-filter assembly 320 , the purified water in the normal temperature water outlet waterway 300 can be post-filtered, thereby improving the taste and quality of the purified water.

[0088] The designer can adjust the specific structure of the rear filter assembly 320 according to the use requirements, and no specific limitation is given here. Preferably, the rear filter assembly 320 includes an activated carbon filter element.

[0089] By connecting the outlet end of the return water circuit 700 to the normal temperature water outlet water circuit 300 located between the fine filter assembly 100 and the post-filter assembly 320, the return water circuit 700 is used to make at least part of the cold water section in the hot water outlet water circuit 500 flow back to the upstream of the post-filter assembly 320, thereby reducing or eliminating the cold water section located in the hot water outlet water circuit 500, making it easier for the water outlet mechanism 600 to quickly output the hot water in the water storage tank 400, thereby improving the user experience.

[0090] Furthermore, after at least part of the cold water section in the hot water outlet waterway 500 flows back to the upstream of the post-filter assembly 320, the post-filter assembly 320 can be used to perform post-filter treatment on the returned water again, thereby ensuring the quality of the water.

[0091] In another possible embodiment of the present invention, Figure 4 In the illustrated embodiment, the water treatment module further includes a pre-filter assembly 220 disposed on the inlet waterway 200 , and the outlet end of the return waterway 700 is connected to the inlet waterway 200 located between the pre-filter assembly 220 and the fine filter assembly 100 .

[0092] By using the pre-filter assembly 220, the purified water in the normal temperature water outlet waterway 300 can be pre-filtered, significantly reducing impurities in the water, thereby facilitating a longer service life of the fine filter assembly 100. Furthermore, the pre-filtered water can be transported to the fine filter assembly 100 for fine filtration to obtain purified water.

[0093] The designer may adjust the specific structure of the front filter assembly 220 according to the use requirements, and no specific limitation is imposed here. Preferably, the front filter assembly 220 includes a front filter composite filter element, which includes a combination of one or more of PP cotton, activated carbon, and phosphate composite filter elements.

[0094] By connecting the outlet end of the return waterway 700 to the water inlet waterway 200 located between the front filter assembly 220 and the fine filter assembly 100, the return waterway 700 is used to make at least part of the cold water section in the hot water outlet waterway 500 flow back to the upstream of the fine filter assembly 100, thereby reducing or eliminating the cold water section located in the hot water outlet waterway 500, making it easier for the water outlet mechanism 600 to quickly output the hot water in the water tank 400, thereby improving the user experience.

[0095] Moreover, after at least part of the cold water section in the hot water outlet waterway 500 flows back to the upstream of the fine filter assembly 100 , the return water can also be used to rinse the fine filter assembly 100 , thereby facilitating extending the service life of the fine filter assembly 100 .

[0096] In another possible embodiment of the present invention, Figure 5 In the illustrated embodiment, the water treatment module further includes a pre-filter assembly 220 disposed on the inlet waterway 200 , and the outlet end of the return waterway 700 is connected to the inlet waterway 200 located upstream of the pre-filter assembly 220 .

[0097] By connecting the outlet end of the return water circuit 700 to the water inlet circuit 200 located upstream of the front filter assembly 220, the return water circuit 700 is used to make at least part of the cold water section in the hot water outlet water circuit 500 flow back to the upstream of the front filter assembly 220, thereby reducing or eliminating the cold water section located in the hot water outlet water circuit 500, making it easier for the water outlet mechanism 600 to quickly output the hot water in the water tank 400, thereby improving the user experience.

[0098] Moreover, after at least part of the cold water section in the hot water outlet waterway 500 flows back to the upstream of the front filter assembly 220, the front filter assembly 220 can be used to re-filter the returned water to prevent the returned water from affecting the water quality of the water outlet mechanism 600.

[0099] In an embodiment of the present invention, the front filter assembly 220 is disposed upstream of the booster pump 210. The booster pump 210 can drive water in the water inlet channel 200 into the front filter assembly 220, thereby regulating and stabilizing the flow rate, so that the water outlet mechanism 600 can discharge water more stably.

[0100] Furthermore, after the water is pre-filtered by the pre-filter assembly 220 , the impurities in the water are significantly reduced, thereby reducing the scale in the booster pump 210 , which is beneficial to extending the service life of the booster pump 210 .

[0101] The booster pump 210 can provide one-way transport on the water inlet channel 200, allowing water to flow toward the water outlet mechanism 600. When the outlet of the return water channel 700 is connected to the normal temperature water outlet channel 300 located between the fine filter assembly 100 and the post-filter assembly 320, or when the outlet of the return water channel 700 is connected to the water inlet channel 200 located between the pre-filter assembly 220 and the fine filter assembly 100, or when the outlet of the return water channel 700 is connected to the water inlet channel 200 located upstream of the pre-filter assembly 220, the driving action of the booster pump 210 can cause the cold water section in the hot water outlet channel 500 to flow from the water inlet of the return water channel 700 to the water outlet of the return water channel 700, without the need for an additional power mechanism, thereby reducing equipment costs.

[0102] In one embodiment of the present invention, the water treatment module further includes a reflux control valve 710 disposed on the reflux waterway 700. By disposing the reflux control valve 710 on the reflux waterway 700, the reflux control valve 710 can be used to control the on / off state and flow rate of the reflux waterway 700, thereby providing greater adjustment convenience.

[0103] The designer can adjust the specific structure of the reflux control valve 710 according to the use requirements, and no specific limitation is imposed here. Preferably, the reflux control valve 710 is a solenoid valve.

[0104] In another specific embodiment of the present invention, Figure 7 In the embodiment shown, the return waterway 700 is provided with a reduced diameter section 720, the radial dimension of which is smaller than the radial dimension of the return waterway 700. Designers can adjust the specific shape and size of the reduced diameter section 720 according to usage requirements, and no specific limitation is imposed here.

[0105] By providing the reduced diameter section 720 on the return water channel 700 and making the radial dimension of the reduced diameter section 720 smaller than the radial dimension of the return water channel 700 , there is no need to provide a valve body on the return water channel 700 , thereby reducing equipment costs.

[0106] When the hot water outlet valve 520 on the hot water outlet waterway 500 is closed, the water pump 510 or the booster pump 210 can drive the cold water section in the hot water outlet waterway 500 to flow from the water inlet end of the return waterway 700 to the water outlet end of the return waterway 700. During this process, the cold water section can freely pass through the reduced diameter section 720, thereby improving the passing efficiency.

[0107] When the hot water outlet valve 520 on the hot water outlet waterway 500 is opened, the hot water outlet waterway 500 is used to transport the hot water in the water storage tank 400 to the water outlet mechanism 600. During this process, the return waterway 700 is restricted by the reduced diameter section 720, and the reflux volume of the return waterway 700 is small, which will not affect the hot water output of the hot water outlet waterway 500.

[0108] In the embodiment of the present invention, the water outlet mechanism 600 includes a faucet, and the normal temperature water outlet waterway 300 and the hot water outlet waterway 500 are connected to the faucet. Designers can adjust the specific structure of the faucet according to usage needs, and no specific limitation is made here.

[0109] By connecting the normal temperature water outlet water path 300 and the hot water outlet water path 500 to the faucet, the faucet can be used to deliver normal temperature water, hot water or a mixture of normal temperature water and hot water, with better adjustment flexibility, thereby meeting the user's needs for water of different temperatures.

[0110] Implementation Method 2

[0111] Please refer to Figures 1 to 5 As shown, a water treatment system is provided in an embodiment of the present invention, which includes a housing, the water treatment module described in embodiment one, and a control module. The control module is electrically connected to the water treatment module, and the control module can be used to control the water treatment module so that the water in the hot water outlet waterway 500 flows back to the upstream of the inlet of the water storage tank 400 through the return waterway 700.

[0112] The specific structure, operating principle, and beneficial effects of the water treatment module are the same as those in the first embodiment and will not be further described here. By utilizing the water treatment module, the water treatment system can return water in the hot water outlet waterway 500 to the upstream of the inlet of the water storage tank 400 through the return waterway 700, reducing or eliminating the cold water section in the hot water outlet waterway 500, facilitating the rapid output of hot water from the water storage tank 400 by the water outlet mechanism 600, and thus improving the user experience.

[0113] Among them, the control module is electrically connected to the water treatment module, and the control module can control the working status of components such as the water pump 510, the booster pump 210, the hot water outlet valve 520, the water replenishment valve 311, and the reflux control valve 710, so that the cold water section in the hot water outlet waterway 500 can flow back to the upstream of the inlet of the water storage tank 400 through the reflux waterway 700.

[0114] Although the water treatment system utilizes a water treatment module to allow the water in the hot water outlet channel 500 to flow back upstream of the inlet of the water storage tank 400 via the return water channel 700, the hot water re-entering the hot water outlet channel 500 will still cool in the hot water outlet channel 500, forming a cold water segment, which prevents subsequent users from obtaining hot water immediately. Therefore, how to better utilize the return water channel 700 to return the cold water segment and improve the return efficiency has become a technical problem that needs to be solved urgently.

[0115] In order to solve the above technical problems, in a feasible embodiment of the present invention, the control module includes a timing unit, and the control module controls the water treatment module based on the time signal of the timing unit to make the water in the hot water outlet waterway 500 flow back to the upstream of the inlet of the water storage tank 400 through the return waterway 700.

[0116] By setting a timing unit, the control module controls the water treatment module based on the time signal of the timing unit to make the water in the hot water outlet waterway 500 flow back to the upstream of the inlet of the water storage tank 400 through the return waterway 700, thereby realizing the effect of timed reflux, thereby periodically eliminating the cold water section in the hot water outlet waterway 500, allowing users to quickly obtain hot water, thereby improving user experience.

[0117] Designers can adjust the timing mode of the timing unit based on user needs, and this is not a specific limitation. For example, the timing mode of the timing unit can be adjusted based on the user's water usage habits. When the user does not need water, the water in the hot water outlet waterway 500 is returned to the upstream of the inlet of the water storage tank 400 through the return waterway 700 to avoid affecting the user's normal use. Alternatively, the timing mode of the timing unit can be a preset interval time.

[0118] In another feasible embodiment of the present invention, the control module includes a user detection unit, which is used to control the water treatment module based on the human body sensing signal obtained by the user detection unit so that the water in the hot water outlet waterway 500 flows back to the upstream of the inlet of the water storage tank 400 through the return waterway 700.

[0119] When the user approaches the casing, there is a possibility that the user will take water. At this time, the user detection unit can detect the human body sensing signal. The control module is used to control the water treatment module based on the human body sensing signal obtained by the user detection unit to make the water in the hot water outlet waterway 500 flow back to the upstream of the inlet of the water storage tank 400 through the return waterway 700, thereby discharging the cold water section in the hot water outlet waterway 500, with better reflux timeliness, so that the user can quickly obtain hot water, and improve the user experience.

[0120] Designers can adjust the specific structure of the user detection unit according to usage needs, and there is no specific limitation here. Preferably, the user detection unit includes a combination of one or more of an infrared sensor, a face recognition module, a Doppler microwave module, a millimeter wave radar module, and a voice module.

[0121] Furthermore, the designer may determine the installation location of the user detection unit according to the specific model of the user detection unit, and no specific limitation is imposed here. Preferably, the user detection unit is disposed on the housing; and / or the user detection unit is disposed on the water treatment module.

[0122] In another feasible embodiment of the present invention, the water treatment system also includes a hot water safety lock arranged on the casing, and the hot water safety lock is electrically connected to the control module. The control module can control the water treatment module based on the trigger signal of the hot water safety lock so that the water in the hot water outlet waterway 500 flows back to the upstream of the inlet of the water storage tank 400 through the return waterway 700.

[0123] The hot water safety lock on the casing can prevent hot water from accidentally flowing out, thereby reducing safety risks.

[0124] Furthermore, when the user unlocks the hot water safety lock, indicating a need for hot water, the control module, based on the trigger signal from the hot water safety lock, controls the water treatment module to cause water in the hot water outlet waterway 500 to flow back through the return waterway 700 to the upstream inlet of the water storage tank 400. This achieves a cold water return operation, improving the timeliness of the return flow, allowing the user to quickly obtain hot water and improving the user experience. Designers may adjust the specific structure of the hot water safety lock according to user needs and are not specifically limited here.

[0125] In an embodiment of the present invention, the water treatment system further comprises a display screen provided on the housing, the display screen is electrically connected to the control module, and the control module can control the start-up of the display screen based on a user signal obtained by the user detection unit.

[0126] By electrically connecting the display screen to the control module, when the user detection unit can detect a human body sensing signal, it means that the user is approaching the casing. At this time, the control module can control the display screen to start up based on the user signal obtained by the user detection unit, thereby facilitating the viewing of the display information on the display screen, avoiding energy waste caused by the display screen being started for a long time, and also helping to reduce the working time of the display screen to increase its service life.

[0129] By utilizing the reflux waterway 700, the water in the hot water outlet waterway 500 can be returned to the wastewater outlet of the fine filter assembly 100. In particular, when there is a cold water section in the hot water outlet waterway 500, the reflux waterway 700 is utilized to cause at least part of the cold water section to return to the wastewater outlet of the fine filter assembly 100 and be discharged, thereby reducing or eliminating the cold water section in the hot water outlet waterway 500, making it easier for the water outlet mechanism 600 to quickly output the hot water in the water storage tank 400, thereby improving the user experience.

[0130] The specific structure, working principle and beneficial effects of the fine filtration component 100, the water inlet waterway 200 with the booster pump 210, the normal temperature water outlet waterway 300, the water storage tank 400, the heating element, the hot water outlet waterway 500 connected to the water storage tank 400, the water pump 510 and the water outlet mechanism 600 arranged on the hot water outlet waterway 500 in this embodiment are roughly the same as those in the first embodiment and will not be repeated here.

[0131] In an embodiment of the present invention, the water treatment module further includes a wastewater channel 800 , which is connected to the wastewater outlet of the fine filtering component 100 .

[0132] Furthermore, a wastewater control valve 810 is provided on the wastewater channel 800. Wastewater control valve 810 can be used to control the on / off state of wastewater channel 800. Designers can adjust the specific structure of wastewater control valve 810 based on usage needs and are not specifically limited here. Preferably, wastewater control valve 810 is a solenoid valve.

[0133] Furthermore, the outlet of the return waterway 700 is connected to the wastewater waterway 800 and is placed downstream of the wastewater control valve 810. By placing the outlet of the return waterway 700 downstream of the wastewater control valve 810, the on / off state of the wastewater control valve 810 is prevented from affecting the discharge of the return waterway 700.

[0136] The specific structure, operating principle, and beneficial effects of the water treatment module are the same as those in Embodiment 3 and will not be further described here. By utilizing the water treatment module, the water treatment system can reflux water in the hot water outlet channel 500 to the wastewater outlet for discharge through the return water channel 700, thereby reducing or eliminating the cold water section in the hot water outlet channel 500 and facilitating the rapid output of hot water from the water storage tank 400 by the water outlet mechanism 600, thereby improving the user experience.
